Any male of any age, who wears signature black Ray-Ban sunglasses, seem to instantly increase their physical attractiveness by a minimum of fifty percent. Ray-Bans happen to compliment any male's face and overall style. One can easily assume the male has a great sense of fashion if they are wearing Ray-Bans.

Me: "Wow, that guy looks hot."
Zoe: "That's only because he's wearing Ray-Bans."
Me: "True; it must be The Ray-Ban Effect."
